The 2026 WHO dementia guideline says cognitive training may be offered to adults over 65 with normal cognition or mild cognitive impairment to lower risk of cognitive decline. Cognitive training means structured, repeated practice on memory, attention or problem-solving tasks, often guided by a clinician or computer program. The advice is conditional, not a universal prescription. It works best as one question among several to raise at a checkup.

What did WHO actually recommend?
The guideline states clinicians may offer cognitive training to older adults with normal cognition or mild cognitive impairment. The recommendation is conditional with low certainty of evidence, as shown in the WHO evidence review table.
Conditional means benefits are uncertain. A clinician should weigh health history, goals, costs and time before suggesting it.
How much benefit does training give?
Evidence reviewed for the guideline showed only a small average gain on cognitive tests. Analysis from the Yassine Lab at the University of Southern California put the gain at Hedges' g of about 0.25, according to the lab's review of brain-game evidence.
That score reflects test performance, not direct proof that training prevents dementia. Readers should view training as possible support for thinking skills, not a guarantee.
How is training different from staying mentally active?
WHO also encourages cognitive stimulation alongside structured training. Examples include tabletop games, reading, learning new skills and other intellectually engaging activities.
The 2026 edition adds social engagement for the same groups. Shared meals, clubs, volunteering and regular conversation exercise attention, language and memory during interaction.
What else belongs in the same checkup?
Brain activity sits inside a broader prevention plan for adults over 65. United Nations News, reporting on the guideline, notes the plan covers physical activity, healthy diet, tobacco cessation, limited alcohol, and control of hypertension, diabetes and hearing loss in its summary of the WHO guidance.
WHO concluded up to 45% of dementia risk could be prevented or delayed, as reported in the World Health Organization announcement. That figure explains why clinicians link brain training to blood pressure, hearing, mood, sleep and medicines.
Which questions can you bring to a clinician?
Use these prompts to shape a brief visit. Pick the two or three that matter most to you.
- Am I a suitable candidate for structured cognitive training given my memory, health and daily schedule?
- Which type, frequency and length make sense for me, and how will we track change?
- Which everyday activities and social contacts should I keep or add?
- Which blood pressure, diabetes, hearing, sleep and mood measures should we review together?
